What Retaining Walls Are for and When You Need One
Retaining walls stop soil from shifting where the ground isn’t flat. If your yard slopes, these walls hold the soil back and let you use the space without worrying about erosion or collapse.
Most homeowners in Toronto use retaining walls to level out a yard, shape a garden, or support a raised patio or walkway. They can be short or tall, straight or curved, depending on the slope and how much support the area needs.
We build walls using natural stone, stacked concrete blocks, or pre-shaped interlocking units. Stone and concrete work better than brick in our climate. Brick can crack or wear out in Toronto’s winter freeze. A stone or concrete retaining wall holds up longer and needs less upkeep.
If your wall is more than four feet tall, it should be made with a segmental retaining wall system. These interlocking concrete blocks lock together for strength and can handle the pressure from heavy soil. They also come in different patterns and textures that fit into most landscape designs.

Where Retaining Walls Make the Most Impact Around Your Property
Retaining walls are most useful in places where your yard isn’t flat. If you’ve got a slope that’s washing out, a raised area that needs support, or a garden that needs clean edges, a wall solves that.
We install retaining walls for:
- Backyard slopes
- Raised garden beds
- Walkout basements
- Split-level yards
- Patios that need support on one side
- Driveways with uneven ground
These walls keep soil in place and stop water from pooling where it shouldn’t. They also help shape your layout and make steep yards easier to use. Whether you need a low garden wall or a full-height structural wall, we match the design to your property.
Types of Retaining Walls We Build in Toronto
The kind of wall you need depends on the slope, soil type, and what you want the wall to do. We build retaining walls using materials that work well with Toronto’s weather and property layouts.
Here’s what we work with:
- Stone Retaining Walls – Natural or cut stone for a durable, clean look
- Concrete Retaining Walls – Strong and long-lasting with a solid poured base
- Interlocking Block Retaining Walls – Segmental wall systems that lock into place
- Pressure Treated Wood Walls – Used in low walls or decorative garden settings
- Modular Wall Systems – Pre-shaped units like Allan Block and Unilock for faster builds
Each material has its own strengths. Stone looks natural. Interlocking systems offer design flexibility. Concrete gives heavy support. We help you choose based on function and appearance.

Why Retaining Walls Work Well in Toronto’s Terrain
Toronto’s got tricky ground. Some homes sit higher than the street, others have backyards that dip hard. Without something to hold the earth in place, you’ll get shifting soil, pooling water, maybe even cracks near the base of your house.
That’s what retaining walls are for. They keep the slope steady, stop erosion, and let you use more of your yard. If you’re building close to a property line or dealing with runoff problems, a wall gives you control. You shape the ground instead of letting it shift with every storm.
In most cases, we can build without permits. But once you go over a certain height, or if the wall needs support structures, you’ll need to meet the rules. We follow the City of Toronto’s wall and grading regulations and handle the process so there are no surprises. For structural walls, we build to match the specs in the Ontario Building Code.
Besides that, a good wall adds value. You gain space where there wasn’t any. A slope becomes a flat surface for a patio, a garden, or just a clean finish against a fence. It also cuts down on water damage and keeps the soil where it belongs.
Built right, these walls last decades with little to no upkeep. That’s why we use solid stone, concrete block, or interlocking systems—materials that won’t crack or rot in our winters. One build, done properly, and you won’t have to think about it again.
What Toronto Clients Say About Our Retaining Wall Work

Retaining Wall and Load Bearing Wall
Moises was easy to get along with and his advice was very helpful to us and listened to our concerns. His crew were hard workers. We would recommend Moises anytime.

Pillar, Stairs, Removal of Retaining Wall, Parging
This project, which started as a simple removal of a retaining wall and redoing the stairs, turned into something much larger with rebuilding a pillar and making everything structurally sound. We were really impressed by Jose and his crew. They went out of their way to make sure everything was done properly. They worked tirelessly and the end result was fantastic. We could not have asked for better workers. Jose and the crew cleaned up after every single work day, worked through 35 degree heat, and made sure our house is as good as it could possibly be. The stone work ended up being amazing and the brick pillar looks incredible. We asked for them to fill in some simple parging, and they ended up going above and beyond and finished the entire wall. It looks phenomenal. We worked with Ray to order the stone, and he had everything organized so we didn’t even have to think.

We Received Outstanding Service
We contacted A&A in February and received excellent customer service in getting connected to our contractor. Our contractor, Dan V. was amazing; he helped us conceptualize the project (a stone retainer wall), the timelines, cost and products needed in a timely and professional way.
Most of all, however, it was the quality of the work; Dan and his team arrived when they said they would, were great communicators, and the quality of their work was really excellent.
We were so happy with this job that we’ll definitely use the services of this company again and highly recommend to others.

FAQs
Common Questions About Retaining Walls in Toronto
How much does a retaining wall cost in Toronto?
Most basic retaining walls in Toronto start around $4,000. For more complex or taller builds using interlocking or reinforced concrete systems, costs can go higher. Based on data from HomeStars’ Concrete Contractors Cost Guide, the average concrete contractor project runs around $8,555, with high-end work reaching $50,000. We give clear quotes after a site visit—no guesswork.
Do I need a permit to build a retaining wall?
Not always. For short walls under a metre high, usually no. But if the wall holds back a slope or sits close to a structure, we may need to follow the City of Toronto building permit rules. We handle that if it’s required.
What material should I use for retaining walls?
Stone, concrete blocks, or interlocking systems all work. Stone blends in better with landscaping. Interlocking blocks work well for taller or tiered walls. We’ll recommend based on slope, load, and how visible the wall is.
Can retaining walls be repaired?
Yes. If it’s leaning, cracking, or has poor drainage, we check the base and structure. We can rebuild parts or start over if needed. We’ve repaired dozens of walls across Toronto and the GTA.
How long does a retaining wall last?
A well-built wall lasts 20 to 50 years or more. That depends on the material, how it was built, and if proper drainage was installed. We build walls that hold up through freeze cycles and heavy rain.
Does a retaining wall help with drainage?
Yes. It stops water from moving downhill and keeps soil from shifting. We build in drainage stone and pipes behind the wall to keep water pressure off. That’s key in Toronto clay soils.
